making traditions about the subjective
futures date of a remote shame it's
complex it's a little redirect event
around but it might actually be possible
in princess another alternative is just
to let the pre-market solve your problem
so if I want to send a message to a I
could add someone else send that message
on a on that using their own money and
then pay them back they've been back
using the crusher communication via
another mechanism so for example if you
have money on a I could pay you slow
cross charge F in order to put up your
money immediately so you could
revitalize my CDP for me and then I will
think about what F that comes through
slow so I would be chopping up my CEP by
entering into a new debt to someone else
there's a couple like pros here it's
instant the cons are that it's
incredibly complex implementer relies on
Rancher market actors just showing up
you're gonna have to pay some amount of
spread because they're giving us the
quiddity on your behalf even though they
have a strong guarantee that you will
pay them back so there's gonna be
like slippage and crusher the price you
pay will pay more than one shark be
either for each chart a new frequency so
you're gonna pay for this service right
and the creditors can actually extort
you a little bit depending on how this
is structured they know your CTB's going
to get liquidated and they know that
you're going to pay up to that amount up
to the amount you lose and so that the
opportunity to charge you higher rates
based on this case that you're
transferring me for and it doesn't work
for some state if there's any secrets
here you can't give away private keys or
hash free images that are important to
your creditor so you actually can't use
this for some types of contracts all
right now we're getting away from things
that I think could actually be easily
get collected and we're getting into
stuff that is a little more like Wiggly
what we depending on my future research
I only got a couple of these and then
we're gonna break for questions for the
last five minutes okay so we've talked
about charts we have to do an
asynchronous communication across charts
the idea has been placed to synchronize
charts too early so it take ambi and
just move them into the same place and
have a period of time where there's
synchronous and I did not do a very good
job on these theories
don't worry about so for a period of
time we're going to have sheriff
validators between hand people and then
anyone on a or I'm beefing interact with
the other shard and instantly you know
in a single transaction without any
waiting period so it would let me use my
Ethernet sharpie and a CD beyond charge
a one of the ideas is that we free
randomized these parents regularly
hungry they suspend what we invented
charting to fix each one part of the
reason that doesn't scale is because it
has the synchronous transactions is
because all the contracts can interact
with all the other contracts so like we
wanted to sharp things to get away from
this model because it prevents scale so
if we do is synchronous shards or we
have like synchronous periods among
different sharks we're giving up a huge
portion of these scaling advantages of
charting for example if we pair two
sharks that's five through twelve pairs
so we've given up half the scale of our
chain okay and then l2 state we're just
gonna like very briefly touch on this
because nobody has proposed that decent
like commenting the model for it that I
know of there's a lot of interesting
ideas about moving contract state into
in the plasma chains or state channels
or similar constructions one of the main
pushes in e2 is to have what's called
stateless clients where the entire chain
state of any given shard is with the
that are actually using it rather than
in the consensus process where we can
come to consensus on updates to the
group connection of the state rather
than updates to the state it's a bit of
a difficult concept to talk about but
generally speaking this was involved
taking contracts which are a sharpie and
either proposal and putting them into a
shared layer tree system that could
settle for those charts we don't know
what this would look like a lot of
people are very excited about it and I
would think that getting a concrete
design is a couple years off it's okay
so this is the end of my slides for now
do we have any questions about cross
direct communication any way to kind of
think about for that given that they
should repeat that shops available to
appeal the dial compound say hey we're
we're making pretty best market richness
there's 2% shopping suddenly everybody
Oh same time yeah so yeah yeah you're
asking whether there's a risk that
contracts will want to be on the same
chart as other contracts so that they
can interact directly and I think
there's definitely that great split one
of the reasons we all got involved in
the period is because we have variable
smart contracts is because CDP's and
compound can interact charting grapes
that guarantee and makes it asynchronous
interaction so you have weaker
guarantees about how the interaction
effects to use them so compound and
maker a particularly interesting because
compound relies on a shared liquidity
for your compounds rate is dependent on
how much of each asset is in compound
right now and in a shard of ecosystem
there have to be a thousand and 24
different compounds deployed with
different liquidity pools so yeah there
are some pretty concrete advantages to
having a chain with all of the smart
contracts on it unfortunately you know
that's what we invented Chardon to get
rid of because it prevents scale
yes this newspaper
you see
there is ok so just any do any of these
models give privacy of your data
segregation across trains
no today the segregation of public chain
is an impossible task for a concrete
example in aetherium we can always load
the snake tree as a purple tree in a
smart contract to inspect private state
variables so any sort of unashamed
public private public chain privacy is
kind of an illusion we can make it more
difficult to read specific state but we
can't make it impossible to be in that
state if you're talking about like user
oriented privacy like zkp there's the
cash gifts that's kind of we're talking
to cross our communication it's so
LCC North America on
with that connects yeah
all L to requires like some magic
waiting period usually measured in days
one of the nice things about the cross
lengths is that they should finalize
your mistake much quicker than that the
reason we have a multi day waiting
period for l2 is to provide better
security for users because one of the
experience options of all help to
constructions is that a user can get a
transaction launching in the waiting
period so one hour waiting period means
excess a presumption it's likely that
that part of it will be much more
significant than the crushed shirt
communication part of said I might help
you see all right where time's up come
find me afterwards
